Mark Cuban just made one of the boldest predictions about AI you’ll hear this year. And it isn’t about Google, Microsoft or some giant company with a billion-dollar budget.
It’s about one person, working from home, with AI doing the heavy lifting.
“There will be the trillionaire in the basement,” Cuban said in a short interview clip that the venture capital firm Andreessen Horowitz, better known as a16z, posted on October 28, 2026.
Cuban is the billionaire investor many people know from the TV show Shark Tank. When someone who has spent decades judging businesses says the next giant fortune could start in a basement, it’s worth paying attention. Here’s what he said, why it’s good news for small business owners, and five things you can do about it this week.
What Mark Cuban actually said
The clip runs less than two minutes. Here are his main points, in plain English:
- Leaders have to understand AI first. Cuban says the people running a company need to know how AI affects their business. Once they do, he says, they can start “fooling around” with it and find new ways to help customers.
- AI is book smart, not street smart. It knows a lot, but it doesn’t have the instincts of an entrepreneur. It needs a person to guide it.
- Most big companies aren’t there yet. Until the top leaders understand how AI works, Cuban says, it will be very hard for their companies to use it well.
- That’s why now is the moment for entrepreneurs. He says there has never been a better time to be one.
He finished with a picture of the future: one person launching their own “agent swarm.” An AI agent is a program that can carry out a task on its own, like answering emails or researching a topic. A swarm is a whole team of them working together. In Cuban’s view, one smart entrepreneur running a team like that can compete with a company of thousands.
The cookie story that proves his point
Cuban backed up his prediction with a real story. A few months earlier, he sat down with the head of a big consumer food company. The executive was talking about buying other companies to keep up with changing customer tastes, including the boom in GLP-1 weight-loss drugs, which are changing what many people want to eat.
Cuban suggested a quick experiment. They took the company’s best-selling product, a cookie, and asked ChatGPT to design a competitor. The new cookie had to be friendlier to people on GLP-1 drugs and cost less. Cuban asked for everything: a full list of ingredients and materials, where to buy them, and how to get the cookie manufactured.
The answer came back in about three minutes. The executive was stunned. As Cuban tells it, the man had no idea AI could do that.
Think about what that means. A big company has research teams, meetings and months of planning before it tests a new idea. The same first draft of a plan is now available to anyone with a laptop. The head of a giant company and a solo business owner can ask the exact same question and get the exact same answer.
Why the basement beats the boardroom
Cuban’s point about leadership is the part most people miss, and it’s the part that works in your favor.
In a big company, the boss has to learn AI, then convince other leaders, then train the staff, then get approval to try something new. In a one-person business, you are the boss, the leadership team and the staff. The moment you understand how AI works, your whole company understands it.
| What it takes | A big company | You in the basement |
|---|---|---|
| Who has to understand AI | Every top leader, then every team | Just you |
| Time to try a new idea | Weeks of meetings and sign-offs | This afternoon |
| Cost of a failed test | Budgets, careers and reputations | A little time and a small AI subscription |
| Who guides the AI | Whoever has time between meetings | The owner, who knows the customers best |
| How fast it can change direction | Like turning a cruise ship | Like turning a speedboat |
Remember Cuban’s other point, too. AI is book smart, not street smart. It needs a guide who knows the customers, the market and the hustle. That’s exactly what a small business owner brings. You don’t need to out-tech anyone. You need to out-think them, and let AI do the grunt work.
5 ways to act on Cuban’s prediction this week
You don’t need a big plan or a big budget to get started. Here are five simple moves, each one small enough to do in a single sitting.
1. Fool around with AI for 20 minutes a day
Cuban literally said “fooling around” is how you find new opportunities. Treat it like play, not homework. Pick one AI chat tool, like ChatGPT or Claude, and ask it to help with one real task in your business every day. You’ll learn more in a week of play than in a month of reading about it.
2. Run the cookie test on your own business
Take your best-selling product or service and ask AI to design a competitor that is better and cheaper. It may feel uncomfortable, but it’s the fastest way to see where your business could improve before someone else does it. Then ask AI to help you build that better version yourself.
3. Ask AI the question you don’t know the answer to
Cuban made a simple but powerful point: if you have no idea how to use AI in your business, you can ask AI that exact question. Tell it what you sell, who you sell to and what eats up most of your week. Then ask, “Where could AI save me the most time?”
4. Hand off one task to an AI helper
Before you build a whole swarm, start with one agent. Pick a task you do over and over, like writing social posts, answering common questions or researching topics. Let AI handle the first draft, and you handle the final check. That’s the guide-and-helper teamwork Cuban described.
5. Add a second helper, then a third
Once one task runs smoothly, add another. One helper writes, another schedules, another sorts your email. This is how a small swarm gets built, one helper at a time, and how one person starts doing the work of a team.
Here are a few starter questions to copy and use today:
| Ask AI this | What you’ll get |
|---|---|
| “Here is my best-selling product. Design a competitor that is better and cheaper, with a list of what it would take to make.” | Your own version of Cuban’s cookie test |
| “Here is what my business does and how I spend my week. Where could AI save me the most time?” | A short list of tasks you can hand off first |
| “What are my customers frustrated about that no one in my market is fixing?” | Ideas for new offers and products |
| “Walk me through setting up one AI helper for [task], step by step, for a beginner.” | Your first agent, explained in plain English |
The door is open right now
Will everyone working from home become a trillionaire? Of course not, and Cuban isn’t promising that. His point is bigger and more hopeful than any one number. For the first time, the tools that used to belong only to giant companies are sitting on your kitchen table. The big players are moving slowly. You don’t have to.
That’s the real gift in Cuban’s prediction. The gap between a one-person business and a big company has never been smaller, and it’s shrinking every month. The people who start learning now, while the giants are still holding meetings about it, are the ones who get there first.
That’s exactly what we do every other Friday at GeekOutFridays, my live show for small business owners who want AI to do more of the work. We build real tools and AI helpers live, step by step, so you can copy what works and skip what doesn’t. Bring your basement. We’ll bring the robots.
